Description

Glasses frame and glasses for high-power lenses Technical Field The present utility model relates to a spectacle frame for high-power lenses for correcting myopia and spectacles. Background In general, a lens for high myopia is a concave lens having a thickness that increases from a center portion to an edge portion of the lens, and in glasses provided with the lens, there are cases where the lens appears to protrude from a rim when viewed from the side, the contour of a wearer of the glasses appears to be deformed, or the eyes appear to be small, and the like are not ideal in appearance. Therefore, conventionally, the thickness of a lens is made less conspicuous by carving a thin line on the outer surface of a rim so as to make the thickness of the lens thinner, or by applying a thinning process (so-called thinning process) of cutting the edge portion of the lens, and then adopting a method such as a frame made of a lens shape (LENS SHAPE) such as a small oval shape or a circular shape in the vicinity of the center of the lens where the thickness is relatively thin (refer to patent document 1). Patent literature Patent document 1 Japanese patent application laid-open No. 2544616 Disclosure of utility model Typically, when a wearer purchases eyeglasses, the wearer will select a frame having a favorite design and mount lenses on the frame that have a degree suitable for the wearer's vision. In this case, a slightly myopic wearer may choose the frame design without limitation of the lens power. However, as described above, in general, in the case of glasses having a so-called high-power lens for high myopia of-6.00D (diopter ) or more (a negative value is large), a characteristic frame design or the like is adopted to make the thickness of the lens inconspicuous, and the range of the wearer's choice of design is narrowed. Further, with respect to the high power lens, even if the thinning process is performed, it is thicker than the low power lens, and the entire front frame (front) becomes heavy due to the weight, resulting in easy forward displacement of the glasses when worn. In this way, there are specific problems in the high-power lens glasses such as narrowing the selection range of the frame design, the thickness of the lenses being careless, and the glasses being easily displaced due to the weight of the lenses. The present utility model has been made in view of the above-described problems, and an object thereof is to provide a spectacle frame for high-power lenses and spectacles for reducing the problems peculiar to spectacles having high-power lenses for correcting myopia. The glasses frame for high-power lenses for correcting myopia according to one embodiment of the present utility model includes a front frame and a pair of side arms connected to both left and right ends of the front frame, the front frame includes a pair of annular rims defining a lens holding hole for holding the high-power lenses, and a center sill connecting the pair of annular rims to each other, and the pair of annular rims each includes a back surface inclined so that a thickness thereof becomes smaller from an outer peripheral edge toward an inner peripheral edge in at least a part of an outer region of the rim located outside the lens holding hole. According to the present embodiment, the pair of annular rims each have the back surface inclined so that the thickness thereof becomes smaller from the outer peripheral edge toward the inner peripheral edge in the rim outer region, and therefore the outer peripheral edge of the height-measuring lens can be hidden by the outer peripheral edge of the rim outer region. In addition, the weight of the front frame can be reduced by the inclined back surface of the outer region of the mirror rim. Therefore, the thickness of the lens can be reduced, and the problem peculiar to the glasses for high-power lenses such as ease of shifting of the glasses due to the weight of the lens can be solved. In the above embodiment, the thickness in the outer peripheral edge of the rim outer region of the annular rim having the inclined back surface may be larger than the thickness in the outer peripheral edge of the height-degree lens in which the optical center of the single-focal lens having a degree of-10.00D and a refractive index of 1.74 is set at the center of the lens holding hole and cut. In the above embodiment, the thickness in the above inner peripheral edge of the rim outer region of the annular rim having the inclined back surface may be smaller than the thickness in the outer peripheral edge of the height-degree lens in which the optical center of the single-focal lens having a degree of-10.00D and a refractive index of 1.74 is set at the center of the lens holding hole and cut. In the above embodiment, the difference in thickness between the outer peripheral edge and the inner peripheral edge in the rim outer side region of the annular rim having the inclined back surface may be 1mm
